I have been playing around document filter but one thing I failed to understand is, when exactly is insertString method used? I have only seen it use replace or remove methods in almost every general possible scenario I can think of (copy/pasting, manual typing etc). From docs, it says:

Invoked prior to insertion of text into the specified Document.

But every method I tried of text insertion executed replace method.

Can someone please simplify it for me when exactly is this method used?

It's called when `Document#insertString` is called – MadProgrammer Oct 05 '15 at 04:56
You mean when `textField.getDocument().insertString...` is used? (just confirming) – user3271166 Oct 05 '15 at 04:57
